PHP Phar::getVersion() Method: Usage and Examples

PHAR archives can package multiple resources into a single file. Phar::getVersion() Method addresses a specific part of that process: returns the archive API version represented by the Phar header. The examples distinguish archive-level effects from member-level effects.

What Is Phar::getVersion() Method?

Returns the archive API version represented by the Phar header.

Its syntax is:

Phar::getVersion()

This function or method takes no parameters.

Return value: The declared return type is string. This is distinct from both PHP version and Phar::apiVersion().

Requirements: The Phar extension must be enabled. Creating or modifying executable PHAR archives generally requires the phar.readonly setting to be disabled before startup; do not change server configuration just to view this guide.

Important: This is distinct from both PHP version and Phar::apiVersion().

Example 1: Basic Usage

The basic example focuses on the behavior of Phar::getVersion() Method: returns the archive API version represented by the Phar header. Inputs are defined locally or shown as application-controlled paths.

<?php

$archivePath = sys_get_temp_dir() . "/example-package.phar";
$archive = new Phar($archivePath);
echo $archive->getVersion();

The displayed value, file content or return status depends on the input and surrounding environment. Results involving local paths, identifiers or generated files are not fixed values.

Example 2: A Different Use Case

This second example illustrates another input or execution condition for Phar::getVersion() Method. Notice the different checks, arguments, or output handling.

<?php

$archive = new Phar(__DIR__ . "/application.phar");
$version = $archive->getVersion();
var_dump(is_string($version));

This variation matters because this is distinct from both PHP version and Phar::apiVersion().

Practical Example: Working with Archive Entries

The following example demonstrates how Phar::getVersion() Method fits into a more complete file or archive workflow, including inputs and appropriate checks.

<?php

$archive = new Phar(__DIR__ . "/application.phar");
$archiveApiVersion = $archive->getVersion();
echo "Archive API version: " . $archiveApiVersion;

The operation shown is an illustrative script. Adapt the filenames, required permissions, and error handling to your own controlled application environment before running it.

Important Behavior and Edge Cases

• Function behavior: Returns the archive API version represented by the Phar header.
• Limitation: This is distinct from both PHP version and Phar::apiVersion().
• Availability: The Phar extension must be enabled. Creating or modifying executable PHAR archives generally requires the phar.readonly setting to be disabled before startup; do not change server configuration just to view this guide.

Comparison With Related Functions

Use Phar::getVersion() Method for the specific behavior described above. The related operation, Phar::apiVersion(), serves a different purpose; do not substitute it unless that different behavior is intended.

Common Beginner Mistakes

Key Takeaways

• Returns the archive API version represented by the Phar header.
• This is distinct from both PHP version and Phar::apiVersion().
• Related operation: Phar::apiVersion() — Reports the extension API version, which is different from the archive header version.

Phar::getVersion() Method is useful when its specific behavior matches your application requirement. Keep paths controlled, check failures, and handle environment-dependent operations deliberately.
